Villain is a random guy who joined me.
Hands played so far seemed solid, nothing fishy, but expecting him to be a recreational. It was 6am in the Friday morning.
I think equity wise it's a close fold, unless we can put him on some random spazz.
i.e some recs 3-bet 55 or 54s and then would take this line. Best case scenario would be random AK/AQ overcards bluff, but that's optimistic.
Those of you who played HU regularly, what do you think?
In hindsight I think I can also fold pre vs this huge sizing.

This looks like apparently like a semi-bluff. Your flop calling range looks apparently like a lot of pair or pair+draws that want to bluffcatch because of that. This logic makes him do this more often with value. I think he would chose another size with semibluffs, or check. His value range is way ahead in equity, thus, to me, a fold seem optimal in this spot with your hand.
